My invention comprises a carton or container IB which is constructed ofcardboard or some posed within thel same. These parts and theirparticular association will now be described'in detail. I

The carton I0 is constructed from a blank I2 of cardboard or some othersimilar material best shown in Fig. 2. This blank is formed with twolongitudinal scores I3 and Il which extend Y throughout the length ofthe blank. 'I'he blank is fumer formed with a number of transversescores I5, I6, I1 and I3 which form in the blank a front wall 2|, a rearwall 22 and two side walls 23 and 2l which vconstitute the lateral wallsof..` the carton. The marginal portions ot the blank I2, outwardly ofthescores'IS and Il, are slit along lines 25 and 2S which divide theportions of the carton outwardly of said scores intoy upper end wallsections 21, 28, 29 and 30 and lower end wall sections 3 I, 32, 33 and34. In addition a ilap 35 is formed on the front wall 2| which isattached tothe side wall 24 Vforming a tubular-50 structure adapted tobe collapsed or extended. 1

The end wall section 29 is weakened along two diagonal lines 3S and 3lwhich extend from the intersections of the scores I3, I1 and I8 andconverge toward one another. These lines are 55 formed by shearing theblankA I2 at the locality indicated at 38 and perforating the blankalong the locality indicated at 39. The lines of weakaisnaoa the edges55 of apsl 53 and 64. In this mannerV ening 36 and 31 are intersected byother lines of weakening 4I which extend parallel to the scores edge 42of theend section 29. By means of this construction a flap 43 is formedwhich serves as a cover ap for the opening formed in the upper end ofthe carton and which will be presently described-in detail. Thisconstruction further' provides a tongue or tab 4'4 which issuesoutwardly from the flap 43. I t Will readily become apparent by tearingthe tongue 44 along the lines of weakening 4I and the flap 43 along thelines of weakening 39 .that the ilap 43 may be completely freed from theend wall section 29 from which the same was formed.

In the end wall section 21 is formed a notch 45. In the end Wallsections 28 and 30 are similarly formed notches 46 and 41. These notchesare so arranged that, when the wall sections are folded into overlyingpositions, the said notches register with one another and form anopening in the carton, indicated in'Fig. 5 by the reference numeral ,48.

. The bag II is constructed from a water resistreceived Within thecarton I0. The length of the bag II is such that the upper marginal part5| vextends upwardly above the score I3 but is ofA a height above saidscores such that its upper edge 52 falls short of the edge of the cartonwhen the parts are folded together.

The method of filling and closing the carton is as follows. Aspreviously stated the blank I 2 comes in collapsed ltubular form withthe flap 35 secured to the side wall I2. The folded structure is rsterected into tubular form and the bottom.

closure formed on the carton by folding the lower end wall sections 3l,32, 33 and 34 upon one another and gluing the same together.accomplished in the usual manner. .Thereafter the bag II is insertedinto the carton and the invention takes the 'appearance shown in Fig. 3with the marginal part of the bag extending upwardly above the lateralWalls of the carton and along the upper end wall sections 21, 28, 29 and30 which lie irncontinuation of the lateral walls,

The two end wall sections 28 and 30,'together with "then foldedoutwardly. The arrangement of parts, after this operation is completed,is shown in Fig. 4. While the parts are so held Vtwo glue collars arerun over theinner surfaces of'the This is all gluek is applied only tothe corner portions 56 and 51 and to the tab or tongue 44. Itwill benoted that the height of the marginal part5I of bag I I is such that themajor portion of 'the cover flap 43 is covered-'and no glue is appliedthereto. Also the size of the notch 45 is such that glue is applied onlyto the c orner portions 51 of the end section 21. After the glue hasbeen applied, end section 21, together with the flap 54, are foldedinwardly and the corner portions 51 cause to adhere to the outermostsurfaces of the end wall sections 28 and 30. The arrangement of partsafter section 21 has been folded is shown in Fig. 5. End wall section 29together. with flap 53, is next folded upon the end wall section 21 andcaused to adhere thereto through the adhesive applied to the cornerportions 56 of said end wall sec tion. The parts then become arranged asshown in Fig. l. The carton is now completely closed and ready for use.Due to the fact that themarginal portion of the bag is formed intodoubled over flaps on account of the manner in which the parts arefolded together, a tight closure is formed lat the end of the cartonwhich prevents leakage of the contents thereof through the end closure.A

Along an area adjacent the score I3 and on the outer .surface of endwall section 21 is providedprinting indicated at 58 which is of a widthless than the Width of the tongue or tab 44. This printing is of suchnature that it prevents stick ing of the glue to the same, therebyleaving the extreme end of the tab 44 unattached to the carton. Thetongue hence becomes attached to the carton only along a narrow banddesignated by the reference numeral 59 in Fig. 5. When it becomesdesired to open the carton, the tab 44 is grasped and pulled loose fromthe end wall section 21. At the same time the lines of weakening formedby the perforations 4I` causes the tab 44 to become separated from .theremainingportion of the end wall section 29. The iiap 43 next becomesdisengaged from the end wall section 29 due to the shear lines 38, andupon further pulling of the tab 44 away from the end wall section 29said tab is broken along the lines of perforation 39 until both tongueand nap are free from the end wall section 29 to hinge about the hingeformed through the score I3. When raised to aposition in alignment withthe rear wall 22', from which .the flap 43 issues, the opening-6| in thebag II becomes exposed. In the eventrthat the flap 53 is partly adheredto the end wall section 21 the same can readily be disengaged therefromafter flap 4a has been freed so that said flaps may be moved jointlyinto the position shown in Fig.' 6. The contents may now flaps 53 and 54and the end wall sections 21 and.

29. The Vlaag II as stated is constructed of a suitable glue repellentmaterial such as parchment or wax paper. This peventsthe glueY fr 'omadhering to the same and coating only the corner po/rtions 56 and 51 ofthe end wall sections 21 andv 29, extending outwardly beyond vthe flaps53 and 54. The lines of vweakening 36 and 31 are so bepoured out of theybag I I, the flaps 53 and 43 serving as a spout to assist indirecting-the con.- tents of the carton to the desired locality.

To facilitate removal of the contents of the carton certain of the wallsof the carton are formed so that the same will bend giving the rear wall22 and flap 43 a U-shaped formation.

This is accomplished as follows. In the rear wall 22 is provided twodiagonal scores 62 and 63 which extend from the locality of the scoresi1k and I8 up to the score I3 at a point in the middle of the flap 43.Connected with this score is another score 64 which extends directly'across the flap 43 and tab 44. In the end section. 21 are similarlyformed diagonally arranged scores 65 and 66 which commence at theintersections of arranged that they substantially coincide with ScoresI3, l5 and I6 and terminate at the edge' 'gg ofthe notch 45. Similarscores 61, 68 and 69 'are formed in the end wall sections 28, 3U and 29which register with the scores 65 and 66. By means of these scoresfolding of the rear wall 22 and the ap 43 into U-shaped formation isgreatly facilitated.

After the carton has once been opened the same may be reclosed in thefollowing manner. The flap 54 is unattached to the end wall section 21and forms therebetween a pocket 50, Fig. 9. Tab 44 is inserted into thispocket through a slit 'Il formed in the end wall section 29.The'arrangement of parts, after the container has been so closed, isshown in Figs. 7 and 9.

The advantages of my invention are manifest. An extremely simple andpractical reclosing carton is provided which functions positively andeffectively in Ithe desired manner. 'Ihe carton can be constructed byordinary machinery available for the purpose and likewise the carton canbe filled and the ends sealed by machinery now used for the requiredpurpose. The carton can be constructed at no additional expensewhatsoever over and above the cost of cartons of the same style anddimensions. The bag within the carton is utilized for preventingadhesion of the end wall sections to one another where not desired sothat the various parts operate in the desired manner.
